In creating these cement spiral staircases, Rizzi Studio combines a sophisticated design with a perfect technical core. Each of the projects acts as a connection between storeys, enhancing the value of the settings and accommodating the requirements of contemporary living. The self-supporting staircase winds around itself according to the available space in a harmonious upward crescendo to become a fundamental element of interior design as well as a functional feature. Individual prefabricated modules are put together to form self-supporting staircases, with 11 standard diameters of between 125 cm and a maximum of 300 cm, to offer fully customizable projects according to the finishes of the intended surroundings.
The logic behind the installation of Rizzi’s reinforced concrete spiral staircases drastically reduces installation times: individual unrefined steps are shipped and subsequently assembled directly on site. They include the tread, the riser and at either end the stringer which, when assembly has been completed, will form two spiral stringer boards notched to accommodate the reinforcement connecting the starting storey to the landing. The treads and risers can also be clad with wood, stainless steel, ceramic, marble and resin.
